This topic describes how to install a pair
of host interface adapters in
an operational system.
About this task
Note: Leave the enclosure operating with a canister missing
for as little time as possible. Operating with a canister missing
disrupts the airflow and can cause the system to overheat if left
that way too long.
Procedure
Follow the following steps to install a
pair of host interface adapters while
the system continues to perform I/O operations.
- In the management GUI, check the Recommended Actions event log view,
resolve any issues that exist before continuing.
- To safely remove a node canister without disrupting I/O,
refer to Procedure: Removing a node canister.
- Remove the lid from the canister. For instructions, refer to Procedure: Removing and replacing lid of a node canister.
- If the host interface adapter has SFP
transceivers,
remove them. To remove a transceiver, swing the release
handle open and use it to pull the transceiver out of the host interface adapter port
(Figure 1).

transceivers
- Loosen the retaining thumbscrew 1 , as shown in Figure 2.

- From inside the canister, grasp the filler handle 2 and
slide the filler plate toward the thumbscrew to disengage the plate
from the catch slot 4 .
- Remove the filler plate.
- Insert the host interface adapter 3 into
the canister as shown in Figure 2
- Align the mounting bracket of the host interface adapter with
the inside of the host interface adapter aperture
at the thumbscrew end of the canister, ensuring that the tab at the
end of the faceplate is aligned with the catch slot 4 .
- Align the connecting edge of the host interface adapter with
the slot in the host interface adapter connector
inside the canister.
- Apply pressure to the opposite edge of the host interface adapter to
push the adapter into the connector.
- Check that the host interface adapter is
installed squarely in its slot and tighten the retaining thumbscrew 1 .
- Reinstall the lid on the canister. Refer to Procedure: Removing and replacing lid of a node canister.
- If you removed SFP
transceivers in
step 4,
reinstall them. To install a transceiver, push it fully
into the port and close the release handle.
- If you purchased an additional 2-transceiver
option, install the extra SFP
transceivers in
the remaining ports. You can install one or two extra transceivers
in the canister. You must install the same number in both canisters
in the enclosure.
- Reinstall the canister
in the enclosure, replace any cables that were removed, and install
the cables that will connect the host interface adapter to
host systems. Do not attempt to connect the cables to any
host systems until instructed to do so. The canister
restarts. Because the hardware configuration has changed, a node error
(841) and associated alert (1199) are recorded in the system event
log.
- Use the Recommended Action in the management GUI monitoring
page to check and accept the hardware changes. The
node canister restarts as part of this process. When the system restarts,
an alert 1470 indicates that the node canister hardware does not match.
You can ignore this alert.
- Repeat steps 2 to 16 for
the second canister. Before powering off
the second canister, verify that host systems have rediscovered
the first canister so they can fail over it when the second canister
is removed.
- Use the Recommended Action in the management GUI monitoring
page to check and accept the hardware changes reported in the 1199
error. The node canister restarts. The mismatched
hardware error 1470 is automatically cleared.
Results
The
host interface adapters are now installed and ready for use. If you have connected to a Fibre Channel SAN Network, zone your network to include your Storwize® system. When your hosts are configured, you will need to use the operations available in the management GUI Hosts tab to configure their use.
